Chapter 319 Mission Complete

Zhang Heng felt as if he was in an unprecedented earthquake. Everything around him was vibrating crazily, and the shaking of those metal parts made people worry that they would fall apart in the next moment.

The moment the rocket left the ground, the powerful acceleration produced firmly pressed the people in the command module on the aluminum alloy seat. It felt like a gorilla was sitting on your chest. The simple movement of raising the arm has become extremely difficult, but fortunately Zhang Heng has already conducted relevant training in the space center before, and is no stranger to such a situation.

The numbers on the main display board are beating wildly!

... 135 seconds after takeoff, the central engine shut down ... 150 seconds later, the four peripheral F1 engines also shut down, and the fuel in the first-stage rocket had been burned out, and at this time Apollo 11 also arrived at six At an altitude of 18,000 meters.

The explosive device blasted the first-stage rocket and the interstage ring, and the former broke away from the launch escape system on the top of the spacecraft, and fell into the deep sea after running out of speed.

On the other side, the second-stage rocket also started to work. The J2 rocket engine increased the flight speed from the previous 9,200 kilometers per hour to a terrifying 24,600 kilometers per hour, leading the spacecraft into the upper layers of the atmosphere in one fell swoop.

The whole process lasted for a full six minutes, and then the second-stage rocket that completed its mission was also separated, and it was the turn of the third-stage rocket to start the relay ignition, and the speed of Apollo 11 continued to climb upwards, but at this time and just took off Compared with the time, the vibration has been much smaller, although the heavy acceleration is still there.

Until 2.75 minutes after the three-stage rocket was ignited, the engine was shut down, and the spacecraft successfully entered the earth orbit at a speed of 28,000 kilometers per hour.

At this moment, there was joy in the ground control center in Houston, because it meant that the work of the launch phase was successfully completed.

After the main engine was turned off, the thrust dropped to 0 in just half a second, and the pressure on Zhang Heng's chest suddenly disappeared, and he switched to a free fall state, but the seat belt on his body still firmly fixed him on the ground. on the seat.

Although in the real world he has read many books and movies related to spaceflight, he has also witnessed the launch of Shenzhou 5, and at the same time he has fully understood every step of the moon landing program in the Apollo training camp, but But when this moment really comes, being in it, as one of the witnesses, this is indeed a completely different feeling.

Now they are in space 166 kilometers from the surface of the earth. The helmets that have been removed are suspended at hand like feathers, and the earth below them can be seen through the portholes.

It is difficult to describe such a scene in words. A solitary blue planet is moored in the velvety black deep space. The arc-shaped horizon looms in the blue atmospheric mist. Clouds drift silently across the blue ocean. The whole ground is like a huge palette, filled with bright colors, blending with transition colors, those yellow deserts, undulating mountains, dark green rainforest... It gives people an indescribable shock and excitement. move.

Even with Zhang Heng's usual calmness, he was rarely distracted at this moment.

At the same time, a series of system prompts came from his ears

[Appreciate the earth from space, the mission has been completed...]

[will return in 4 days...]

[Successfully ride the Saturn 5 launch vehicle, game points +10, you can go to the character panel to view related information...]

[Successfully entered the earth's orbit, game points +20, you can go to the character panel to view related information...]

[Successfully maintain a continuous weightlessness state for more than 500 seconds, game points +10, you can go to the character panel to view related information...]

"It's beautiful, isn't it?"

Collins also unbuttoned his seat belt, kicked his legs, and floated to Zhang Heng's side, "Once I have seen such a scene once, I will never forget it for the rest of my life. Congratulations, David, you are now a real Astronaut, but you won't get your golden brooch until you return to Earth."

On the other side, there was a rare smile on Armstrong's face. No matter how many times this was his first mission, it was hard not to be immersed in the beauty of the earth when he saw the beauty of the earth from this angle.

But right now they still have other work to do. Apollo 11 will be parked in low-earth orbit for a period of time and fly around the earth. The spacecraft will conduct final inspections here, and then the Saturn 5 will be ignited again. , took them to officially embark on a trip to the moon.

This step is also known as Earth-Moon orbit injection.

So far, although Zhang Heng’s main task has been completed, and he has also gained 50 game points, but there are still more than four days before the return date, and he is in space. Apart from completing the mission to the moon with Armstrong and Collins, he has nothing to do. other options.

After confirming that everything was in good condition and the direction of the spacecraft was correct, the J2 engine of the Saturn 5 ignited again after 148 minutes, and the spacecraft was completely separated from the earth with the remaining fuel.

The Saturn 5 launch vehicle also successfully completed all its missions.

And then it was time to test the three people on the spaceship.

When the entire spacecraft was designed, the lunar module was placed in the protective layer of the rocket. To drag it out, the command/service module needs to be separated first.

After that, the astronauts drove the separated command/service module to rotate 180 degrees, completed a U-turn, returned to the front of the rocket, docked with the lunar module inside, dragged it out, and discarded the useless third-stage rocket.

Although some of this also comes from the help of the ground control center, the entire docking process requires manual operation, and any small error in operation may have disastrous consequences.

"I'll leave the rest to you." Armstrong said to Collins who was on the side.

The latter nodded and took a deep breath.

He manipulated the command/service module and the rocket to successfully separate, completed the flip at a distance of 300 meters, and then re-approached the Saturn 5 at a relative speed of 2 meters per second.

In order to prevent Collins from being distracted, Zhang Heng and Armstrong did not speak during the whole process, but just quietly watched the entire docking process through the porthole above their heads.

Collins used the thrusters to carefully adjust the angle and position of the spaceship, as if picking up a diamond with tweezers. His hand holding the joystick was always steady. Finally, with a slight tremor of the bulkhead, the command/ The small head at the top of the service module inserted into the docking ring on the rocket almost exactly.

At this time, three and a half hours had passed since takeoff, and Apollo 11 officially bid farewell to the earth and flew to the moon 300,000 kilometers away.

This dungeon is coming to an end, it's finally coming to an end... ┭┮﹏┭┮, it's too fucking hardcore, I'm almost even an aerospace enthusiast.
